Technical solution of the present disclosure will be described in detail below with specific embodiments. Several specific embodiments below may be mutually combined, and the same or similar concepts or processes may not be described repeatedly in some embodiments.

With the continuous development of speech recognition technologies, increasingly device has a speech recognition function set therein. A smart speaker has a powerful speech recognition function, in which various operations can be implemented via a speech interaction with the user. Currently, when multiple smart speakers coexist, if the user sends out speech information including a wake-up word, the multiple speakers will response to the wake-up word simultaneously, which make the multiple speakers stay in a listening state. However, if the multiple speakers stay in the listening state simultaneously, it will lead to a chaotic speech interaction, making the live speech broadcast environment noisy and causing a bad user experience.

Aiming at the above-described technical problem, the present disclosure provides a smart speaker wake-up method, a smart speaker wake-up device, a smart speaker and a storage medium, which may be applied to a scenario where multiple smart speakers coexist, so as to quickly select one smart speaker that is most likely to be wakened by the user, avoiding a chaotic speech interaction caused by multiple smart speakers being wakened simultaneously, improving efficiency and quality of speech interaction and achieving better user experience.

FIG. 1 is a schematic diagram of a principle for implementing a smart speaker wake-up method according to embodiments of the present disclosure. As shown in FIG. 1, in the scenario that multiple smart speakers coexist, multiple smart speakers are connected together via a wireless network. When the user sends out speech information, all of the smart speakers in the wireless network can receive the speech information including the wake-up word. And then the smart speaker performs a recognition processing to the speech information to obtain identification information corresponding to the wake-up word. The identification information may be information including a timestamp of receiving the wake-up message by a speech algorithm database, speech intensity of the wake-up word, a node address and the like. For example, the smart speaker may recognize the wake-up word in the speech information via a speech algorithm, and then record the speech intensity of the recognized wake-up word, time at which the wake-up word is recognized and the like. All of the smart speakers in the wireless network would record a first speech intensity and a first timestamp. The first speech intensity represents a distance between the smart speaker and the user, the higher the speech intensity, the less the damage of the sound during transmission and the shorter the distance between the smart speaker and the user. The first timestamp is used for marking the time at which the speech information is received and the wake-up word in the speech information is recognized. And then, the smart speaker transmits the identification information to other smart speakers located in the same wireless network by way of broadcasting. Meanwhile, the smart speaker also receives the identification information transmitted by other smart speakers in the wireless network. Each node of the smart speakers can transmit this kind of information via the wireless network, where the size of package should comply with rules and requirements of the wireless network. And then, according to a preset rule, the smart speaker compares the identification information of itself with the received identification information transmitted by other smart speaker and make a determination, so that one smart speaker in the wireless network is wakened to enter listening state while other smart speakers give up to wake up. A plurality of strategies may be set to solve the problem of simultaneously waking up and recognizing, for example by using a method of comparing the timestamps, where only one terminal having a wake-up timestamp with the earliest time can wake up its system and enter the listening state and then react to the subsequent instructions. Similarly, the problem of simultaneously waking up and recognizing can also be solved by using speech intensity, where the determination would be made by comparing the speech intensity received by each of the nodes, and only the node with the highest signal intensity wakes up itself and switches to the next state while other nodes give up to wake up themselves. These solutions will be described in detail in the following embodiments, which is not described repeatedly herein.

The above-described method can be applied to a scenario where multiple smart speakers coexist to quickly select one smart speaker that is most likely to be wakened by the user, by which the technical problem of a chaotic speech interaction caused by multiple smart speakers being wakened simultaneously is overcame, and one smart speaker that is most likely to be wakened by the user is quickly selected according to the identification information corresponding to the wake-up word, thereby obtaining the technical effects of improving efficiency and quality of the speech interaction and achieving better user experience.

FIG. 2 is a schematic diagram according to the first embodiment of the present disclosure, as shown in FIG. 2, a method of the present embodiment may include:

S101, receiving speech information including a wake-up word.

The smart speaker wake-up method of the present embodiment may be applied to the wireless network including two or more smart speakers. The smart speakers have different wake-up words set therein according to different system configurations, such as “Xiaodu Xiaodu” “Xiaoai Classmate”. The smart speaker can receive the speech information including the wake-up word, so as to enter the wake-up state. However, when there exist two or more smart speakers in the network, multiple smart speakers would response to the wake-up word simultaneously. The purpose of the present disclosure is to quickly select one smart speaker that is the most likely to be wakened by the user and avoid the chaotic speech interaction caused by multiple smart speakers being wakened simultaneously.

Selectively, the smart speaker in the wireless network is located in a preset geographic range, and there exist at least two smart speakers with different account numbers in the wireless network.

Specifically, currently when the user sends out the wake-up word and performs a query, if multiple machines login in by using the same account number, a cloud end would make a judgement according to position and the account number, so as to issue a following query consequence to only one of the speakers instead of all of the speakers with the same account number. However, when the multiple machines login in by using different account numbers, all of the multiple machines would be wakened and respond respectively to the query content, in this case, due to reasons of network transmission and terminal load, the site would become very noisy after the query content is issued, which leads to a bad user experience. The present disclosure can quickly select one smart speaker that is most likely to be wakened by the user among local choices, therefore it is applicable to a scenario in which at least two smart speakers with different account numbers exist in the wireless network, i.e. the method of the present disclosure can be adapted to waking up the local smart speaker no matter what kind of account numbers are used by multiple local smart speakers to login in.

S102, performing a recognition processing to the speech information to obtain identification information corresponding to the wake-up word.

In the present embodiment, the smart speaker performs the recognition processing to the speech information and obtains the identification information corresponding to the wake-up word. The identification information may include a timestamp of receiving the wake-up message by a speech algorithm database, speech intensity of the wake-up word, a node address and the like.

S103, waking up one smart speaker in the wireless network to enter listening state according to the identification information.

In the present embodiment, the smart speaker transmits the identification information to other smart speakers located in the same wireless network by way of broadcasting. Meanwhile, the smart speaker also receives the identification information transmitted by other smart speakers in the wireless network. Each node of the smart speakers can transmit this kind of information via the wireless network, where the size of package should comply with rules and requirements of the wireless network. And then, according to a preset rule, the smart speaker compares the identification information of itself with the received identification information transmitted by other smart speaker and make a determination, so that one smart speaker in the wireless network is wakened to enter listening state while other smart speakers give up to wake up. A plurality of strategies may be set to solve the problem of simultaneously waking up and recognizing, for example by using a method of comparing the timestamps, where only one terminal having a wake-up timestamp with the earliest time can wake up its system and enter the listening state and then react to the subsequent instructions. Similarly, the problem of simultaneously waking up and recognizing can also be solved by using speech intensity, where the determination would be made by comparing the speech intensity received by each of the nodes, and only the node with the highest signal intensity wakes up itself and switches to the next state while other nodes give up to wake up themselves. These solutions will be described in detail in the following embodiments, which is not described repeatedly herein.

It should be illustrated that the present embodiment defines no limitations to a sequence of transmitting the identification information by way of broadcasting via the smart speaker and receiving the identification information transmitted by other smart speakers in the wireless network, where, transmitting may be followed by receiving, receiving may be followed by transmitting, or transmitting and receiving may be simultaneously performed.

In the present embodiment, by means of receiving speech information including a wake-up word, performing a recognition processing to the speech information to obtain identification information corresponding to the wake-up word, and waking up one smart speaker in the wireless network to enter listening state according to the identification information, the smart speaker wake-up method may be applied to a scenario where multiple smart speakers coexist, so as to quickly select one smart speaker that is most likely to be wakened by the user, avoiding a chaotic speech interaction caused by multiple smart speakers being wakened simultaneously, improving efficiency and quality of speech interaction and achieving better user experience.

All of the smart speakers in the wireless network would record the first timestamp for marking time at which the speech information is received and the wake-up word in the speech information is recognized.

S203, transmitting the first timestamp to other smart speakers in the wireless network by way of broadcasting, and receiving a second timestamp transmitted by other smart speakers in the wireless network.

In the present embodiment, the second timestamp is referred to as time corresponding to the recognition of the wake-up word by other smart speakers. When the wake-up word is recognized by the smart speaker from the speech information via the speech algorithm, the smart speaker may transmit the time corresponding to the recognition of the wake-up word (the first timestamp) to other smart speakers in the wireless network the way of broadcasting. Other smart speakers will record the received time corresponding to the recognition of the wake-up word as the second timestamp. When there are multiple smart speakers in the wireless network, the smart speaker may receive the time transmitted by other smart speakers for many times, therefore there may multiple second timestamps being recorded.

It should be illustrated that the present embodiment defines no limitations to a sequence of transmitting the first timestamp by way of broadcasting by the smart speaker and receiving the second timestamp transmitted by other smart speakers in the wireless network, where transmitting may be followed by receiving, receiving may be followed by transmitting, or transmitting and receiving may be simultaneously performed.

Specifically, each of the smart speakers in the wireless network implements a task of comparing the first timestamp with the second timestamp, gives up to wake up if the time of at least one second timestamp is earlier than the time of the first timestamp, i.e. the present smart speaker is not the first smart speaker in the network that recognizes the wake-up word; and wakes up to enter the listening state if none of the time of the second timestamp is earlier than the time of the first timestamp, i.e. the present smart speaker is the first smart speaker in the network that recognizes the wake-up word. By this way, the smart speaker can be wakened according to the time at which the wake-up word is obtained, an earlier time of obtaining the wake-up word illustrates a shorter distance between the smart speaker and the user. Therefore, the smart speaker closest to the user in the wireless network can be wakened to enter the listening state, thereby avoiding a chaotic speech interaction caused by multiple smart speakers being wakened simultaneously, improving efficiency and quality of speech interaction and achieving better user experience.

In the present embodiment, by means of receiving speech information including a wake-up word, performing a recognition processing to the speech information to obtain identification information corresponding to the wake-up word, and waking up one smart speaker in the wireless network to enter listening state according to the identification information, the smart speaker wake-up method may be applied to a scenario where multiple smart speakers coexist, so as to quickly select one smart speaker that is most likely to be wakened by the user, avoiding a chaotic speech interaction caused by multiple smart speakers being wakened simultaneously, improving efficiency and quality of speech interaction and achieving better user experience.
